Countries by Nuclear Energy Share of Electricity 2025

About This Dataset

Countries ranked by the percentage of national electricity generation derived from nuclear power plants in 2025, according to IAEA Power Reactor Information System and IEA Electricity Statistics. France generates approximately 70% of its electricity from nuclear power — the highest share of any large economy and the product of a deliberate energy policy decision made after the 1973 oil crisis to achieve electricity independence through a standardised fleet of pressurised water reactors built at industrial scale by state utility EDF. This nuclear dependency has given France among the lowest carbon intensity electricity in Europe and among the cheapest wholesale electricity prices, though it has created a concentration of infrastructure risk that became apparent during the drought-related reactor cooling crisis of 2022.

✨ AI Insight

France's dominance in nuclear energy, with a staggering 70% share, is a testament to its long-term energy policy established post-1973 oil crisis. In contrast, Slovakia and Ukraine, with shares of 58% and 55% respectively, show a strong commitment to nuclear energy as well, although they are considerably behind France. Belgium and Hungary follow with 50% and 48%, indicating a regional trend towards nuclear dependency in Central and Eastern Europe. Notably, the United States, with only 18.6% of its electricity from nuclear, highlights a significant gap in nuclear adoption compared to its European counterparts. This disparity may stem from differing public perceptions of nuclear safety and energy policy priorities.
